Title: Automatic focusing device
Inventor: OGASAWARA AKIRA
IPC: G03B13/36
Filed: 1982-09-14
Abstract: PURPOSE:To perform matching of the response speed and the damping characteristics of each lens, by constituting the device with plural photographic lenses and a camera body and driving a lens driving motor with a motor driving current which is changed in accordance with driving characteristics of photographic lenses. CONSTITUTION:The light transmitted through a photographic lens 1 is focused onto a sensor 2 constituted with a CCD or the like. The output of the sensor 2 is digitized by an A/D converter 3, and the deviation from the focus position is detected in an operating device 4 by a known method, and a control output corresponding to this deviation is transmitted to a driving circuit 6 by a controller 5. The photographic lens 1 is moved by a motor 7 which is driven by the driving circuit 6, and the extent of movement detected by a movement extent sensor 8 is fed back to the controller 5. The controller damps the lens when the feedback pulse and the output of the device 4 have a prescribed relation. The circuit 6, the motor 7, and the sensor 8 are provided in the lens structure body.

Title: Damper device for spool valve
Inventor: OOKUBO HITOSHI
IPC: F15B13/04
Filed: 1979-12-07
Abstract: PURPOSE:To prevent hunting without spoiling accelerativity of the spool by interposing a piston between pilot pressure chambers and damping chambers and providind these damping chambers with relief valves. CONSTITUTION:Pistons 12, 13 are installed between pilot pressure chambers 8, 9 and damping chambers 10, 11. The stroke S, until the external end of a rightward traveling spool 1 comes into collision against a piston 13 is set larger than the lap length L. Accordingly, an orifice 17 works to actuate the spool 1 early to an extent of minute necessary position in which no hunting arises in order to prevent the lag of start. In the stroke S2 from the spool's 1 contacting the piston 13 to further traveling to the right, damping effect is obtained almost merely by the setting pressure for the relief valve 15.

Title: Production of hollow steel ingot
Inventor: FUJII TETSUYA
IPC: B22D7/04
Filed: 1981-10-06
Abstract: PURPOSE:To produce superior hollow steel ingots having roughly uniform wall thickness in high yields by charging molten steel into a mold from below and drawing the formed solidified shell upward. CONSTITUTION:In a mold 2, molten steel 4 is charged therein from below, and is cooled with a cooling jacket 20. While the solidification of the steel 4 is under progression, a holding metal 8 is immersed into the steel 4 in the position where a solidified shell 6 forms, and the metal 8 is solidified and captured in the shell 6. At the point of the time when the prescribed shell 6 is formed, the metal 8 is pulled upward, and the shell 6 is removed easily from the inside of the mold 2. The replenishing of the steel 4 according to drawing of the shell 6 is accomplished by providing an intermediate vessel 12 below a ladle 10, and communicating the mold 2 and the vessel 12 with a bottom charging runner 14. The level of the molten steel in the mold 2 to be charged with the molten steel is maintained at a specified position easily by maintaining the level of the molten steel in the vessel 12 at the same level as the height of the specified position where the molten steel is charged in the mold 2.

Title: Flat panel display device and plasma display device
Inventor: TSUCHITANA SHIGETOSHI
IPC: H05K9/00
Filed: 1998-06-08
Abstract: PROBLEM TO BE SOLVED: To prevent the deformation of a protective panel of a flat panel display device, more particularly an electromagnetic wave absorption filter of a PDP to a rugged shape by its thermal deformation, etc., and the generation of moires by the contact thereof with the image display surface of the PDP unit and further, to eliminate the need for separate conductive members exclusive of fixing members at the time of fixing the electromagnetic wave absorption filter and a front part casing. SOLUTION: The electromagnetic wave absorption filter 2 is fixed onto the outer flank 5S of a frame portion 5 forming an aperture 1a of the front surface of the front part casing 1 by a conductive double coated adhesive tape 8 having flexibility in a direction parallel with the adhesive surface. As a result, the deformation of the electromagnetic wave absorption filter 2 by its heat or moisture is absorbed by its own elastic deformation of the double coated adhesive tape 8. Even more, the double coated adhesive tape 8 itself has electrical conductivity and, therefore, there is separately no need for the conductive fixing members.

SOLUTION: When an electromagnetic coil is energized, a plunger 18 is pulled against an upper spring 19, a closing valve 31 is released from a closing valve seat 27, and a repelling energy is reserved in the spring 19. Then, when the coil is de-energized, the plunger 18 is returned downward by the repelling energy of the spring 19. With the repetition of the processes the plunger is reciprocated and an intake valve 33 disposed in the plunger 18 and a discharge valve 44 disposed downstream opens and closes alternately, thereby enabling the pumping action. When a driving input is interrupted, the plunger 18 seats the valve 31 on the seat 27 by the load difference between the springs 19, 20 and an intake side passage is closed, thereby surely preventing flowing out of oil.

Title: Production of optical disk master and production of master stamper
Inventor: UENO FUMIAKI
IPC: G11B7/26
Filed: 1998-06-08
Abstract: PROBLEM TO BE SOLVED: To provide a producing method of an information medium having low noise and high density in which the area of a groove edge part is decreased and irregularity in the groove edge is prevented. SOLUTION: A photoresist film 2 is formed to almost λ/(2×n) thickness, wherein λ is the wavelength used for exposure and n is the refractive index of the photoresist at that wavelength, and the film is exposed and developed to form a desired photoresist pattern. Then the substrate 1 is subjected to anisotropic etching and the photoresist is removed. By this method, the intensity of the exposure light is reduced on the photoresist surface by the interference, which decreases irregularity in the edge of the photoresist pattern after development. By using the photoresist pattern as a mask to etch the substrate 1 by anisotropic etching, irregularity in the groove edge is prevented, the groove edge is not rounded, and the groove edge has a large angle to give a small edge area. Therefore, an information medium having low noise and high density can be produced.

Title: Load detector
Inventor: KOBAYASHI KIYOTO
IPC: G01G3/15
Filed: 1995-06-26
Abstract: PURPOSE: To obtain a compact and inexpensive load detector which can detect the load accurately while exhibiting durability against heavy load. CONSTITUTION: Variation in the load on an object is converted through a resilient member, i.e., disc spring 5, 6, into positional displacement which is then detected by a position sensor 7. Consequently, a load detector can be built in an object compactly and inexpensively and even a heavy load can be detected effectively. When the disc springs 5, 6 are set with different spring constants, both the durability against heavy load and the high accuracy detection of light load can be satisfied. Furthermore, when the disc springs 5, 6 are applied with liners 12, 13 having high hardness, the assembled state is prevented from deteriorating due to behavior of the disc springs 5, 6 and the detection accuracy can be sustained effectively.
